This is where I struggle not to laugh at you and dox myself when you suggest I don’t know massively more than you about shipping in general and Mediterranean shipping in particular. Let’s just say that my job leaves me extremely well-placed on the subject, and that if you have anything to do with shipping or the sea in your professional life you almost certainly use my products.
I will say, confidently, that you know nothing about what you’re talking about, here.
Oh by the way have you yourself ever sailed? Me I’ve sailed all over the Great Lakes in an actual sail boat. By the way the Great Lakes are also considered rougher than the Mediterranean Sea. If you actually did some research you would fine out that the Mediterranean is considerably calmer than the Atlantic with smaller waves and much more predicable weather.
Here’s a comparison of the Mediterranean to the Atlantic
Mediterranean Sea
Generally calmer: It is known for its warm, calm, and clear waters, especially during the summer months.
More protected: Being a relatively enclosed sea, it is less exposed to the large swells and strong winds common in open oceans.
Seasonal variations: It can still become rough, particularly in the fall and winter due to winds and storms, but it is generally less consistently rough than the open Atlantic.
Atlantic Ocean
Typically rougher: Open oceans like the Atlantic are less protected and are more prone to larger waves and stronger, more consistent winds, especially in higher latitudes.
Calm periods: However, the Atlantic can have very calm periods, such as the "doldrums" in the equatorial regions or during settled high-pressure systems.
Vast and varied: The Atlantic is a huge body of water, and its calmness varies greatly by location. For example, the northern Atlantic is generally rougher than the southern part
